Skyler buys a bag of cookies that contains 9 chocolate chip cookies, 5 peanut butter cookies, 9 sugar cookies and 7 oatmeal rais

sergiy2304 [10]

Answer: $\dfrac{7}{145}$ .

Step-by-step explanation:

Given ,The bag contains :

9 chocolate chip cookies, 5 peanut butter cookies, 9 sugar cookies and 7 oatmeal raisin cookies.

Total cookies = 9+5+9+7=30

Now , the number of ways to choose any two cookies ( one after another) :

$^{30}C_2=\dfrac{30!}{2!(30-2)!}=\dfrac{30\times29\times28!}{2\times28!}=435$

The number of way to choose two oatmeal raisins ( one after another) :

$^{7}C_2=\dfrac{7!}{2!(7-2)!}=\dfrac{7\times6\times5!}{2\times5!}=21$

Now , the probability that Skyler randomly selects an oatmeal raisin cookie from the bag, eats it, then randomly selects another oatmeal raisin cookie will be :

$\dfrac{21}{435}=\dfrac{7}{145}$

Hence, the required probability is $\dfrac{7}{145}$ .

Find the sum of the first 44 terms of the following series, to the nearest integer. 10, 14,18,...

Daniel [21]

Answer:

4224

Step-by-step explanation:

Here, we want to calculate the sum of the first 44 digits

Term a which is first digit is 10

common difference which is difference of terms = 14-10 = 18-14 = 4

Now the nth term of an arithmetic sequence is

a + (n-1)d

44th term means n = 44

10 + (44-1)4

10 + 43(4)

10 + 172 = 182

To find the sum, we use the formula

Sn = n/2[a + L]

where a is the first term and L is the 44th term

Sn = 44/2 (10 + 182)

Sn = 22(192)

Sn = 4,224
